Patented ean, 1913.

Application filed February 17, 1911, Serial No 609,170 Renewed February24, 1913. Serial No. 750,415.

To all whom, it may concern:

Be it known that I, ROBERT M. Jones, a citizen of the. United States,residing at 1142 Humboldt street, having oflices at 805 Ideal Building,Denver, county of Denver, State of Colorado, have invented a new anduseful Process of Forming and Making Concrete Poles, Piles, and Columns,of which the'following is a specification.

This invention relates to the process of forming concrete -intocylindrical form, either solid concrete from its center to its surface,or formed around an internal core to its surface, including ampleprovision for embedding reinforcing steel longitudinally in and throughthe cylindrically formed article, all to be accomplished without the aidof an exterior form or mold.

This process of forming reinforced poles, piles and columns without theuse of exterior forms, I accomplish by enveloping concrete in a heavyflexible belt material, the belt to be somewhat longer than the articleto be formed, and in width equal to twice the circumference of thearticle to be formed in its largest part. The forming of the concreteinto a round cylindrical form is accomplished by revolving themass ofconcrete one or more revolutions slowly up and down an inclined plane,ohcausing the belt,

and mass to be formed, to revolve one or more revolutions alternately inone direction thence in the opposite direction upon and encircled in aseries of rollers having approximately the same size and shape of thearticle to be formed. In either or anyv event, the belt and thesurfaceof the article being formed of concrete shall travel throughoutthe length of the article being formed, at proportionate velocity,thereby preventing a twisting or torsional movement'of the mass ofconcrete while it is in the process of being formed. For forming taperedarticles such as poles, the proportionatequantity of concrete will bedistributed to cause one end to be larger than the other. In suchinstances the enlarged diameter of the work must be driven atproportionately greater velocity, by. such procedure articles fnay beformed having forced concrete poles, piles and; columns upon which Ihave submitted to the United States Patent Oflice this day anapplication for patent.

Together with this, my application for patent upon Process for formingreinforced concrete poles, piles and columns, I submit drawings (onesheet) illustrating two applications of the process.

In the drawings, Figure 1, represents a perspective view of an apparatuspreferably employed in the practice of my, process, with the mass ofplastic material in the po sition it occupies while being molded, and,Fig. 2, a view in perspective of unmodified construction of theapparatus, likewise showing the plastic article in the position itoccupies in the practice of my process.

Fig. 1 is described first, wherein, A represents the article beingformed, which revolves or turns in the belt B as the belt is raised orlowered. B represents the flexible belt material which envelops the'article inclined plane upon whichthe flexible belt B and article beingformed will travel in a revolving manner. v Fig. 2 is described second,wherein, D

represents the article being formed, it revolves upon and in theflexible belt E in unison with the travel of the belt E and rollers F. Erepresents the flexible belt material which envelops the article beinformed,-'it rests upon and revolves simu taneously with rollers F, thebelt E terminates at either side with a weighing down strip. Frepresents a series of rollers built practically of the same diameterand taper which the article formed shall rep resent when completed.These rollers partially encircle the article being formed and are to beoperated by gears of even ratio causing all rollers represented torevolve at the same velocity and in the directions represented byindicating arrows.

I claim class described, consisting in imparting to a body of plasticmaterial, a revolving motion by reciprocatory movement of a surface uponwhich it is loosely supported.

2. The process of molding-articles of the class described, consisting inimparting to a direction transverse to said axis.

r and Whose opposite end is 4. The process of molding articles of theclass described, consisting in imparting to a body of plastic material arevolving motion about a longitudinal axis by a reciprocating movementin a direction transverse to said axis, ofthe free end of a sagging,flexible surface upon which it is loosely supported,

fixed.

5. The process of molding articles of the class described, consisting inembedding a core in a body of plastic material, imparting to the lattera revolving motion in a direction transverse to the axis of said core,by movement of a surface upon which it is loosely supported, andremoving the core after the material has become hardened.

6. The process of molding articles of the class described, consisting inembedding re inforcing devices in a body of plastic material andimparting to said body, a revolving motion by movement of a surface uponwhich it is loosely supported.

7. The process of molding articles of the class described, consisting inimparting to a body of plastic material of longitudinally decreasingcross-sectional area, a revolving motion about its longitudinal axis bymove ment of a surface upon which it isloosely supported, transverse tosaid axis at rates of speedvarying at different points of the saidsurface in ratio to the circumferences of said body at the said points.
